Question

1. what is the vitally important natural resource contained in the oceans of the world? why is this resource difficult to obtain from the oceans?

Explanation:

The vitally important ocean resource is freshwater (from seawater). Seawater has high salt content, so desalination is needed; this process requires significant energy, infrastructure, and cost, making large-scale extraction challenging.

Answer:

1. The vitally important natural resource is freshwater (extractable from seawater).
2. It is difficult to obtain because seawater has a high concentration of dissolved salts. Removing these salts requires energy-intensive desalination processes (like reverse osmosis or distillation), which are costly to implement and operate at a large scale, and also require specialized infrastructure that is not widely accessible in all regions.
